I've managed to play through the game (and the two previous ones) up to chapter five, dead men tell no tales.

Running into several minor bugs with this level but have hit a showstopper where bentleys bombs don't appear to have any affect on the enemies (where they did in previous levels) and the grapplecam automatically explodes upon deployment. (where it didn't in previous levels)

Searching on the internet it appears that these bugs are emulation problems rather than problems with the game itself. There are one or two threads (linked below) that offer fixes, but don't present enough information for an incredibly rookie user such as myself or are solved by the original poster without an exchange of information.

It is my hope that you can show me where i'm going wrong and help me come to a solution.
Many Thanks
